CONCORD, N.H. (AP) — New Hampshire, home to the first-in-the-nation presidential primary, also got a jump-start on general election voting.

Two tiny communities, Dixville Notch and Hart's Location, opened their polls at midnight and closed them minutes later. President Barack Obama and Republican nominee Mitt Romney had a tie vote in Dixville Notch and Obama picked up a win in Hart's Location.

Elsewhere, the earliest voters can go to the polls in other communities is 6 a.m., with the last polls closing at 8 p.m.

Secretary of State William Gardner is predicting 722,000 people will cast ballots in the tightly contested presidential race. That amounts to 70 percent of New Hampshire's voting age population.

Voters also will pick a new governor, decide close races for two congressional seats and cast ballots for 400 state House seats and 24 state Senate seats.
